Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic lunch boxes, and in particular to a modular plastic lunch box. Background Technology
[0002] In today's fast-paced lifestyle, people's demand for convenient dining is growing. Plastic lunch boxes, because they can meet the needs of different food packaging and carrying, have been widely used in scenarios such as food delivery, outdoor picnics, and portable meals for office workers.
[0003] Currently, most common modular plastic lunch boxes on the market are fixed, one-piece structures. During use, food is stored by placing it inside the lunch box. However, in the process of storing food, it is inevitable that multiple foods need to be stored. When different foods are placed inside the same plastic lunch box, flavors often mix, which affects the normal consumption of the food. Utility Model Content
[0004] To overcome the problem that existing plastic lunch boxes cause different foods to mix and have flavors cross-contaminated inside due to their one-piece structure.
[0005] The technical solution of this utility model is: a modular plastic lunch box, including an inner liner component, a bowl component movably connected to the lower end of the inner liner component, a set component movably connected inside the inner liner component, and a cover component movably connected to the set component.
[0006] The bowl assembly includes a smooth bowl assembly and a ribbed bowl assembly;
[0007] The kit components include a smooth sleeve assembly and a ribbed sleeve assembly;
[0008] The inner lining assembly includes a fixed ring cover movably connected to the bowl body assembly, an inner lining body connected to the fixed ring cover, and an inner groove formed on the inner lining body.
[0009] The cover assembly includes a sealing cover movably connected to the kit assembly, a guide strip connected to the sealing cover, and an exhaust hole formed on the sealing cover.
[0010] Preferably, the smooth bowl assembly includes a first bowl body movably connected to the inner liner body, a first limiting ring connected to the first bowl body, a first sealing ring connected to the first limiting ring, and a first opening piece connected to the first sealing ring.
[0011] Preferably, the smooth sleeve assembly includes a first positioning ring movably connected to the sealing cover, a first sleeve connected to the first positioning ring, and a first opening piece connected to the first positioning ring.
[0012] Preferably, the ribbed bowl assembly includes a second bowl movably connected to the inner liner body, an anti-slip rib formed on the second bowl, a second limiting ring connected to the second bowl, a second sealing ring connected to the second limiting ring, and a second opening piece connected to the second sealing ring.
[0013] Preferably, the ribbed sleeve assembly includes a second positioning ring movably connected to the sealing cover, a second sleeve connected to the second positioning ring, a fixing rib formed on the second sleeve, and a second opening piece connected to the second positioning ring.
[0014] The beneficial effects of this utility model are:
[0015] 1. This utility model uses a separate structure of inner lining component, bowl body component, set component and lid component to enable the lunch box to store different foods in categories during use. At the same time, the number of bowl body components can be increased or decreased to accommodate different amounts of food, thereby reducing food waste to a certain extent. The detachable bowl body component and set component facilitate thorough cleaning of hard-to-reach corners and avoid oil stains, thus greatly improving the comfort of using the entire modular plastic lunch box.
